Skarn-hosted gold-silver-copper mineralization is developed within the sedimentary rocks along the contacts of intrusive rocks as well as within altered dykes of the skarn envelope….Mineralization at Media Luna is hosted in skarn that developed at the contact of the intrusive granodiorite and overlying sedimentary rocks. The skarn is characterized by a mineral assemblage of pyroxene, garnet, and magnetite. Metal deposition and sulfidation occurred during retrograde alteration and is associated with a mineral assemblage comprising amphibole, phlogopite, chlorite, and calcite ± quartz ± epidote as well as variable amounts of magnetite and sulfides, primarily pyrrhotite. Additional mineralization is associated with skarn developed within and along dykes and sills above the main granodiorite intrusion”.
